402. The Five Stairsteps, 'O-o-h Child'

"O-o-h Child" gave the Five Stairsteps — four brothers and a sister from Chicago — a pop-soul classic that rivaled the hits of another sibling gang, the Jackson 5. The children of police detective Clarence Burke, the Five Stairsteps, who played their own instruments as well as sang, ranged in age from 13 to 17 when Curtis Mayfield signed them to his Windy C label.
